Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of polyimides and polyamides that exhibit excellent thermal stability and mechanical strength. Commonly applied in aerospace, electronics, and insulation materials for high-temperature environments. Also serves as a crosslinking agent in advanced composite systems and finds use in the development of specialty coatings and adhesives requiring durability under extreme conditions. Its aromatic structure with multiple amine groups enables efficient curing and network formation in resin formulations.
